HD Tune is a Hard Disk utility which has the following functions:
Benchmark: measures the performance
Info: shows detailed information
Health: checks the health status by using SMART
Error Scan: scans the surface for errors
HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has gained popularity amongst reviewers. It is now considered a must have application for storage device testing.
As of now, M.2 drives, both SATA and PCIe, use a driver provided by Microsoft built into Windows 7 and Windows 8. A110 supports ATA-8 / ACS-3 Standard register and command sets. At some point, we expect new drivers, either from manufacturers or from Microsoft, that are optimized for the faster interface. The performance we experienced was very good, but anyone who's compared the Microsoft AHCI driver to Intel's PCH SATA driver knows that performance gains are possible.
In HD Tune Pro's sequential read test the A110 256GB delivered more than 130 MB/s more performance than any other 256GB SSD we have in the charts today. The sequential read performance wasn't just a burst peak and then the drive slowed considerably. SanDisk designed the drive to deliver good sustained performance.
The minimum sequential write in HD Tune Pro was nearly 500 MB/s. The maximum and average were right around 550 MB/s. The performance average was over 100 MB/s over the SanDisk Extreme II, one of the fastest sequential writing drives on the market today.
HD Tach - Sequential Write Performance after Random Writes
After a realistic number of random writes from the HD Tune Pro random tests, we measure sequential read and write performance with HD Tach, full drive span and 128KB blocks.
When reading data with the larger block size, the A110 took off to just under 650 MB/s. More importantly, the sequential writes didn't fall to the bottom of the chart like some of the newer controller / flash combinations do.
